Locations of buried objects
The top of a parabolic form waveform represents the surface of the buried
object.
When the scene is set to “Dry Concrete” or “Wet Concrete,” burial detection
marks appear all in the same size irrespective of the width of each buried
object.

Burial detection marks may appear in
misaligned positions due to the effects of
concrete honeycombs or other
irregularities in concrete.
In that case, estimate the correct location
from the waveform in the image.
In the image as shown in the right
example, point (a) is the correct location.
When a yellow marker does not appear
as well, the estimation may be possible
from the image.
